Paper Abstract

The APART code (Arizona's Paraxial Analysis of Radiation Transfer) is a deterministic stray radiation analysis program capable of yielding quantitative descriptions of systems along with insight into the scattering mechanism present. APART uses y-y geometrical optics to image primarily rotationally symmetrical sys-tems. APART provides a sectional power map of the internal surfaces of a system and identifies "critical" objects seen from the image. Vane structures are modeled by configuration factors. Once the geometrical configuration factor between the internal objects has been calculated and stored, nonstructural changes to the system can be analyzed without re-running the complete program.
